Determining if a coworker is a natural blond is easy when you know what to look for. Tips for discovering dye jobs.
The most obvious way to tell is by looking at their roots. No matter how careful a person is to upkeep their hair color, it is inevitable that signs will show at the root. At the rate that hair grows, all one needs is about two weeks worth of growth for color differences to be noticeable. The best place to spot a person's roots is at their hairline. This is especially true of the temple and nape of the neck. Many times the hair at the temple is shorter, and sheds quicker. Thus the new growth will be more obvious, as it won't have older, dyed hair attached to it. The nape of the neck is also a good place to spot roots, as most people dye their hair only to the base of the neck. On either side of the base, the hair continues to grow down the neck. This hair is usually neglected in the hair dying process.
An additional way to tell if someone dyes her hair is by the shades of color in their hair. Natural hair has up to seven shades of the natural color. The lighter shades are in the front, and the hair darkens as you proceed to the back of the head. This is because the front and top receive maximal sun exposure, in comparison to the back of the hair. Someone who dyes their hair will have one color from the front to the back.
Some people highlight their hair for a more natural look. But this technique does the contrary. Highlights are purposefully placed, and nature does not highlight one's hair precisely. Instead highlights, look more like streaks, instead of shade variations, which is what natural highlighting looks like. If you are around someone consistently, you will notice dyed hair fading over time. The brightness will diminish into flatness after a couple of weeks. Sometimes with blonds, pool chlorine will leave a greenish tint to their hair. Determining if your coworker is a natural blond is easy when you know what to look for. But remember, if they keep it a secret, so should you.
